Abstract

A vehicle chassis is a shaped metal sheet chassis body or member with regions of relatively low torsional rigidity, and regions of relatively higher torsional rigidity. At least some of the low torsional rigidity regions are reinforced with a composite overlay comprising directionally oriented long fibers of carbon or the like which may be woven into a mat of directionally oriented fibers and embedded in a matrix of resin or the like. The overlay increases the regions of the chassis to which is applied without significantly increasing the weight of the chassis.
